You need to represent it as 2x + 10 = 50
Answer: r - 5 = 8
Step-by-step explanation:
From the question, we are informed that Skye ran r laps today at soccer practice while Nadine ran five fewer laps than Skye.
If Nadine ran eight laps at practice, the equation that can be used to find how many laps Skye ran will be:
r - 5 = 8
This means Skye ran 13 laps
ANSWER
A. x = 2, √11, -√11
EXPLANATION
To find the zeros of f, which is a 3rd-degree polynomial, we can try some common values to see if any of them is a zero: 1, 2, -1, -2. In this case 2 is a zero of the function:
Now we can reduce our polynomial by dividing it by the factor (x - 2) and obtain a 2nd-degree polynomial, whose zeros are easier to find:
So we can rewrite f(x) as:
To find the other two zeros we have to solve:
Add 22 to both sides of the equation:
Divide both sides by 2:
And take square root. Remember that the square root has a positive and a negative result:
So the other two zeros are √11 and -√11.
The three real zeros of f are 2, √11 and -√11
The values of is 2 and r are -1 of the geometric series and it can be determined by using geometric summation operation.
Given that,
The geometric series is,
2 – 2 + 2 – 2 + 2
We have to determine
What are the values of a1 and r of the geometric series?
According to the question,
<h2>
Geometric series;</h2>
2 – 2 + 2 – 2 + 2
The geometric series is the first term of the geometric sequence and r is the common ratio of the geometric series.
The first term of the given geometric series is 2.
And the common difference in the given geometric series is,
Where is the first term of the geometric sequence and is the second term of the geometric sequence.
Then,
The common difference in the given geometric series is,
The common ratio in the given geometric series is -1.
Hence, the values of is 2 and r is -1 of the geometric series

Answer:
y= 5x
Step-by-step explanation:
since each x number is 1/5 of the y, it's 5 times x = y
